5. Addon Preferences

Additional settings for NOVA ARC can be found in Blender's Addon Preferences (Edit > Preferences > Add-ons, then find NOVA ARC and expand it if necessary, or click the "Preferences" button if viewing from the N-Panel after searching).

Performance Tuning

• Overlay Update Interval (sec): Controls how frequently (in seconds) the addon re-calculates measurements and updates the overlay.

  • Lower values (e.g., 0.1) mean faster updates and more responsiveness but higher CPU usage.

  • Higher values (e.g., 0.5) mean less frequent updates (more lag) but lower CPU usage.

  • Default is 0.2 seconds.

• Max Vertices Limit (Edges): This is a crucial performance setting.

  • When measuring based on selected edges, if the total number of unique vertices forming those edges exceeds this limit, the addon will skip the "max distance from edges" calculation and will not display recommendations based on it. This prevents significant slowdowns when very dense meshes or large portions of a mesh are selected via edges.

  • This limit also applies if you select more than two vertices directly; if the count of directly selected vertices exceeds this limit, the "max distance between selected vertices" calculation is skipped.

  • The measurement between exactly two selected vertices is not affected by this limit and is always performed.

  • Default is 300 vertices.
